Procedure
A solution of 4.67 g (0.029 mol) of 2-(2-hydroxyethyl) isoindoline and 3.72 g (0.029 mol) of ethyl acetoacetate was heated at 100°-110° C. under nitrogen for 36 hours. Ethanol was removed with nitrogen flow during the course of the reaction. The mixture was subjected to flash chromatography (silica gel, 1:1 ethylacetate/petroleum ether) to give 1.54 g (22%) of a dark oil. NMR (CDCl3) δ 2.2 (3H, s), 2.94 (2H, t), 3.4 (2H, s), 3.9 (4H, s), 4.24 (2H, t), 7.04 (4H, s)
